I have noticed with the Adafruit cable that the serial connection
sometimes just stops when I reboot or cycle the power.

The following seems to reliably restart the serial port:
   * Leave the serial cable connected.
   * Remove power from the BBB
   * Press and hold the boot switch
   * Plug power back in while holding the boot switch.
   * Count to three and release the boot switch

Finally, of course, are you sure that your cable is
supported by your laptop?   USB-to-serial adapters
seem to be surprisingly variable.
